PART 4 "GETTING IT RIGHT" COLORIMETRIC INSTRUMENTAL TESTING METHODS (DIGITAL) As we turn our attention to the use of digital testers (Colorimeters) such as the HANNA CHECKER, most of the same elements necessary for good precision and accuracy that exist in Visual Testing also exist in Digital...

PART 3 -----COLORIMETRIC VISUAL TESTING METHODS (What We See) SOURCES OF ERROR IN THE ASSESSMENT PROCEDURE Next we turn to the second component of our testing protocols and that is the ASSESSMENT…What do we see and how do we interpret the results of our testing procedure. Visual colorimetric...

PART 2-----COLORIMETRIC VISUAL TESTING METHODS (The Chemistry) As we covered in Part 1 in the “Understanding Errors” section, the visual testing method consists of essentially two steps, Evaluation and Assessment. Evaluation is the test procedure (The Chemistry) and Assessment is the...
